Does StringCollectionContainsClaim throws an exception if collection is empty?

I'm trying to check if the e-mail provided by the user is in the otherEmails claim, but if the user has no e-mail in the list, an error message appears and i can't find a way to translate it.

Transformation:

            <ClaimsTransformation Id="AssertEmailIsInOtherEmails" TransformationMethod="StringCollectionContainsClaim">
                <InputClaims>
                    <InputClaim ClaimTypeReferenceId="otherMails" TransformationClaimType="collection" />
                    <InputClaim ClaimTypeReferenceId="email" TransformationClaimType="item" />
                </InputClaims>
                <InputParameters>
                    <InputParameter Id="ignoreCase" DataType="string" Value="true"/>
                </InputParameters>
                <OutputClaims>
                    <OutputClaim ClaimTypeReferenceId="passwordResetEmailIsInOtherEmails" TransformationClaimType="outputClaim"/>
                </OutputClaims>
            </ClaimsTransformation>

This is the message: "Unable to validate the information provided."

    Hi @DervanilJunior-4636 · Welcome to Q&A platform and thanks for your query.

    The problem with empty string collection is, we cannot infer an empty list to be of type string collection. It could be of some other type as well. There is a bug already open with product team for this issue. However, there is no ETA for a fix as of now.

    Hi, it works this way, using this two policies the correct message is shown.

                <ClaimsTransformation Id="CheckIfOtherMailsPresent" TransformationMethod="DoesClaimExist">
                    <InputClaims>
                        <InputClaim ClaimTypeReferenceId="otherMails" TransformationClaimType="inputClaim" />
                    </InputClaims>
                    <OutputClaims>
                        <OutputClaim ClaimTypeReferenceId="isOtherMailsPresent" TransformationClaimType="outputClaim" />
                    </OutputClaims>
                </ClaimsTransformation>
    
                <ClaimsTransformation Id="AssertIsOtherMailsPresentIsTrue" TransformationMethod="AssertBooleanClaimIsEqualToValue">
                    <InputClaims>
                        <InputClaim ClaimTypeReferenceId="isOtherMailsPresent" TransformationClaimType="inputClaim" />
                    </InputClaims>
                    <InputParameters>
                        <InputParameter Id="valueToCompareTo" DataType="boolean" Value="true" />
                    </InputParameters>
                </ClaimsTransformation>
    

    Thank you.
